WINDMILL ATTACHMENT.

Specification of Letters Patent.

Application filed June 28, 1916. Serial No. 106,417.

tachment and is designed to be secured on the lower end of a vertically reciprocating rod that is connected to the crank of the windmill shaft for coupling said rod to a piece of mechanism designed to be operated by the windmill.

The principal object of the invention is to provide in such an attachment means for quickly connecting and disconnecting the actuated mechanism, such as a pump from the windmill rod, without stopping the movement of the windmill and at any point in the operation of the mechanism by the simple operation of turning a lever that forms a coupling between the windmill rod,

and the mechanism.

A further object of the invention is to provide an attachment for the purpose described which shall be simple in construction, of few parts, easily attached, and which may be operated by any person however unskilled to disconnect the windmill from the mechanism operated.

Vith these as theprincipal objects in view, the invention consists in the novel construction and combination of parts now to be described and claimed and illustrated in the accompanying drawings, in which- Figure 1 is an elevation of the attachment connected to the lower end of a windmill rod and to the upper end of a pump rod.

Fig. 2 is an elevation of the same parts viewed from the right of Fig. 1;

Fig. 3 is an enlarged view of the coupling mechanism, portions being shown in section; and

Fig. 4.- is a horizontal sectional view on the line H of Fig. 2.

In the drawings, 10 indicates the lower end of a windmill rod which is moved vertically in the well-known manner by a connection at its upper end with the crank on a windmill shaft, not shown. 11 is the upper end of a vertical pump cylinder from the upper end of which extends a piston rod 12 which may be operated manually whenever desired by a handle 13 pivoted at 14:

to the cylinder 11 and to the pump rod or piston at 15. A guide bracket 16 extends up from the cylinder 11 to a point above the handle 13 and has an opening therethrough for the piston or pump rod 12 to slide freely therein.

Attached to opposite sides of the windmill-rod 10 and projecting below the lower end of said rod are cheek plates 17 held Patented May 1, 1917.

firmly to said rod bybolts 18. The lower ends of the cheek plates which extend below the rod 10 are offset inwardly to bring their extremities 19 into closer but parallel relation and are so maintained by a rivet or bolt 20 passing through said extremities a short distance below the offset portions.

Pivoted in the upper forked end 21 of the pump rod 12 is a connecting link 22 having near its upper end a notch 23 extending inwardly from one side and adapted when said link is swung upwardly into line with the pump rod to straddle the rivet or bolt 20, as shown in Fig. 3. A short-distance below the notch 23 and on the opposite side thereof is an offset 24, on one side of which is pivoted by means of a pin 25 the hub 26 of a lever 27, said lever being curved as at 28, beginning at the hub in the form of a quadrant and then continuing downwardly tangentially to the quadrant portion to a point near the pivot 29 of the link 22. The quadrant portion of the lever 27 passes freely through an eye 30 that extends outwardly from the lower end of one of the cheek plates 17. A hook 31 fastened to the link 22 and extending from one side thereof serves to hold the lower end of the tangential portion of the lever 27 when the latter is engaged therewith.

In operation the parts are in the position shown in full lines in the drawings where it will be seen that the windmill rod 10, pump rod 12 and link 22 are in line, the link 22 fitting snugly between the extremities 19 and on the cheek plates with the rivet 2O engaging the notch 23 in the upper end of said link and held in this position by the lever 27 which, passing through the eye 30 has its lower end.in engagement with the hook 31. As thus connected the operation of the windmill will reciprocate the pump rod 12, the pivot 15 connecting the hand lever 13 of the pump may be removed if desired. When the windmill is to be disconnected for the purpose of operating the pump by hand or for any other reason, the lever 27 is disconnected from the hook 31 and swung upwardly on its pivot 25, the movement causing the link 22 to become disconnected from the pin 20 and swing away from the windmill rod and into position shown by dotted lines in Fig. 2. In this position the rod 10 will continue its reciprocating movement but being disconnected from the link will have no effect thereon, the lever 27 alone swinging with the rod 10 upon its pivot 25. The pump rod 12 may now be connected to the handle 13 if the pin 15 has been removed and further operation of the pump continued by hand. Coupling the pump to the windmill rod 10 may be easily eflected by leaving the pump rod sufliciently high to permit the link 22 when swung in vertical position to engage the pin 20 through its notch 23 as said rod 10 moves either upwardly or downwardly, and, when so cou pled, the lever 27 is forced downwardly into engagement with the hook 31.

What is claimed is:

1. A windmill attachment and connecting means comprising a link pivotally connected to one part and separately connected to another part, a lever pivoted to the movable end of said link and slidably connected to the second-named part to swing without moving the first named part when the link is disengaged, and means on the link adapted to lock the lever and hold said separable part in inseparable connection.

2. A windmill attachment comprising in combination with an operating means and a means to be operated, of a link pivoted to one of the means aforesaid, a separable connection adapted to be separably connected to the other of said means, a swinging lever pivoted to said link at the separably connected end and adapted to be held by its free end to the opposite end of said link and to one of said members for lockingthe separable connection against disconnection.

3. In a windmill attachment, the combination with an operating means and a means to be operated, of a connecting link therebetween, said link being pivotally connected to one of the means aforesaid and separably connected by a hook-like connection to the other of said'means, an eye on the lower end of said means, a lever pivoted near the free end of said link and adapted after passing through said eye to extend along the said link and be connected thereto at its lower end to securely lock said separable connection against separation.

4:. In awindmill attachment,the combination of a windmill rod, plates projecting beyond the lower end thereof in parallel relation and having a rivet or bolt extending therebetween, a pump rod or the like, a link pivoted to said pump rod and having a laterally extending notch in its upper end to engage said rivet or bolt and form a separable connection between the pump rod and windmill rod, a lever pivotally connected to the link near its notched end, an eye on the lower end of one of said plates through which said lever extends and curving down-.

wardly is engaged at its lower end against movement by a hook on the lower end of said link.

5. In a windmill attachment, the combination of a pump rod, and a link pivotally connected to its upper end, said link having a lateral notch in one edge near its upper end, a windmill rod, plates bolted to the opposite sides of the lower end of said rod and projecting below the same'in parallel relation between which plates said link is adapted to pass, a bolt or rivet between said plate extensions with which said notch is .adapted to engage and connect said windmill rod and pump rod, an offset on said link below the notch and on the opposite sides of the link therefrom, a lever having a curved quadrant upper end terminating in a hub pivotally connected by means of said hub to said offset, an eye on the side of one of said plates at its lower end through which said quadrant end of the lever passes, and a hook near the lower end of the link to engage the lower end of said lever and lock the same against movement and the link in separable engagement with the windmill rod. In testimony whereof I aflix my signature in presence of two witnesses.
